TO: ALL UNIT 1 TECHNICALISPECIFICATIONS MANUAL HOLDERS By amendment 168 to the Unit 1 Technical Specifications, the NRC authorized relocation of certain fuel-related limits from the Technical Specifications to the adjunct Core Operating Limits Report (COLR). This letter transmits to all Unit 1 Technical Specifications manual holders a copy of Revision 0 of the COLR for Hatch 1 Cycle 16. This document should be utilized in conjunction with the Unit 1 Technical Specifications, as referred to in the Specifications. Normally, the shift tecimical advisor or reactor engineer will use this report.

Where necessary, the fuel limits from the COLR are included in plant procedures.

Please discard Revision 1 of the COLR for Hatch 1 Cycle 15, which was issued in May 1993, since it is no longer applicable. If you have questions regarding Revision 0 of the Unit 1 COLR for Cycle 16, please contact me at extension 8-821-7392 or telephone number (205) 877-7392.

EDWIN L HATCH NUCLEAR PLANT UNIT 1 FUEL CYCLE 16 CORE OPER ATING LIMITS REPORT

1.0 INTRODUCTION

The Core Operating Limits Report (COLR) for Plant Hatch Unit 1 Cycle 16 is prepared in accordance with the requirements of Technical Specification 6.9.1.11. The core operating limits presented herein were developed using NRC-approved methods (References 1 and 2), Results from the reload analyses for the General Electric (GE) fuel in Unit 1 Cycle 16 are documented in References 3 and 4.

The following cycle-specific core operating limits are included in this report:

a. Operation with a Limiting Control Rod Pattern (for a Rod .

Withdrawal Error (RWE)) - Technical Specification 3.3.F.  :

b. Average Planar Linear Heat Generation Rate (APLHGR) -

Technical Specification 3.11.A.

c. Minimum Critical Power Ratio (MCPR) - Technical Specifications 3.11.C and 4.11.C.
d. Linear Heat Generation Rate (LHGR) - Technical Specification 3.11.B.

2.0 LIMITING CONTROL ROD PATTERN (Technical Specification 3.3.F)

Both Rod Block Monitor (RBM) channels shall be operable as specified in Technical Specification 3.3.Fand when: i

a. THERMAL POWER is < 90% of RATED THERMAL POWER and the MCPR is < 1.70 or
b. THERMAL POWER is .>_90% of RATED THERMAL POWER and the MCPR is < 1.40.

Revision 0 1 October 1994

Plant Hatch Unit 1 Fuel Cycle 16 Core Operating Limits Report 3.0 APLHGR LIMITS (Technical Specification 3.11.A) l The APLHGR limits are given by the applicable rated-power, rated-flow limit l taken from Figures 3-3 through 3-8, multiplied by the smaller of either: )

a. The factor given by Figure 3-1 or
b. The factor given by Figure 3-2.

For the fuel types whose APLHGR limits are shown in Figures 3-3 through 3-8, the APLHGR limit shall be applied to each axial location in the fuel assembly.

As required by GESTAR Amendment 19, the hand-calculated APLHGR values for a multi-lattice (i.e.,GE9-330, GE9-331, and GE13-LUA) fuel must be less than or equal to the APLHGR limits shown in Figures 3-4,3-7, and 3-8, respectively. When APLHGR values are determined by the process computer, the lattice-dependent APLHGR limits are used. Under these conditions, some axial locations may have APLHGR values exceeding the values shown in Figures 3-4,3-7, and 3-8.

i Plent Hatch Unit 1 Fuel Cycle 16 Core Operating Limits Report 4.0 MCPR OPERATING LIMITS (Technical Specifications 3.11.Cand 4.11.C)

The MCPR operating limit (OLMCPR) is a function of fuel design, average enm time, core flow, number of operating recirculation loops, operability of c:M of-cycle recirculation pump trip (EOC-RPT) system, and core power. Note th:.i in Fipr 4-3, the rated-power and rated-flow OLMCPR is fuel-type dependent; e ;?..the Option B limits are 1.29 for GE7 and GE9 fuels, and 1.41 for GE13 fuel. The values shown in Figure 4-3 apply to all combinations of operating strategies for all exposures when the EOC-RPT systern is operable.

4.1 Two Recirculation Loon Operation For 25% .<_ power < 30%, the OLMCPR is given in Figure 4-1. For power _> 30%, the OLMCPR is the greater of either:

a. The applicable limit determined from Figure 4-2 or
b. The appropdate K,given in Figure 4-1, multiplied by the appropriate limit shown in Figure 4-3 where the scram time dependenc: is given in Technical Specification 4.11.C.2.

4,2 Single Recirculation Iron Operation For single-loop operation, the OLMCPR shall be 0.01 greater than the two-loop value which is determined as specified in Section 4.1.
